Specification

Method for producing health food containing dietary fiber

Field of the invention

The present invention relates to a method for granulating a food material containing dietary fiber, and a health food produced by the method.

Conventional technology

[0002] In recent years, various health foods containing green plants have been developed and used in consideration of prevention of lifestyle-related diseases and the like. Such health foods can be provided to consumers as products of various shapes. Among them, foods that are provided in powder or granular form and are dissolved or dispersed in water immediately before consumption are popular.

[0003] For example, Japanese Patent Application Laid-Open No. 2003-339350 discloses a diet food containing wheat leaf and xylo-oligosaccharide. It is described that this diet food can be mixed with excipients and binders and formed into various shapes such as tablets and granules. Depending on its shape or taste, it can be eaten as it is, or it can be dissolved in water, hot water, milk, etc. and drunk. However, this document does not describe a granulation method, particularly a granulation method using water.

[0004] Japanese Patent Application Laid-Open No. 2002-218945 has an object that, as a subject, a dietary fiber-containing food is preferably in a dry form from the viewpoint of storage stability, and from the viewpoint of ease of handling and portability, is more preferable than a powder form. Also, it is preferable to form (granulate) into tablets, granules, fine granules and the like. However, consumers have found that the addition of excipients and binders such as cellulose-dextrin (a component formulated for the purpose of shaping food) makes the health food material as pure as possible rather than fortified. It is said that it wants to be prepared only with water-soluble derivatives of pregelatinized starch, pullulan, chitin, water-soluble derivatives of chitosan, chitin oligosaccharides and chitosan oligosaccharides. A method of granulating by adding one or more binders selected from the group below is proposed. However, in the method of this document, granulation is performed after dissolving the binder in water, so granulation is troublesome, and the amount of use is limited when a binder having low solubility is used. [0005] Therefore, there is a need for the development of an effective technology that is easier to operate and that can easily granulate even when only water is sprayed on food materials.

Disclosure of the invention

Problems to be solved by the invention

[0006] The present invention provides a dietary fiber-containing granular or fine health food which is easy to handle and can be easily dissolved or dispersed in water or the like for consumption by a consumer, and a method for producing the same. provide.

[0007] The present invention also reduces the use of ingredients, such as excipients and binders, which are not directly related to the original function of the health food, in producing a health food in the form of granules or fine granules containing dietary fiber. Provided is a health food and a method for producing the same.

Means for solving the problem

[0008] The method of the present invention uses xylo-oligosaccharides as an alternative to binders. That is, when granulating a powdery food material containing dietary fiber, xylo-oligosaccharide is added to the food material prior to or during the granulation step, and the granulation is performed. It is a method of producing food.

[0009] In the present specification, a dietary fiber-containing food material means a portion of a leaf, a bud, a stem, a flower, a fruit, a root, an ear, a seed, a fruit, etc., which mainly contains plant fiber, and typically includes , Young leaves of green plants. Examples of preferable food materials include food materials for producing so-called green juice, and examples thereof include powdered ash tapa, powdered young barley, green tea powder, kale, or a mixture of at least one of them. is there. Ashitaba is preferred because it is rich in antioxidant vitamins. Other examples of dietary fiber-containing food materials that can be used are described in many documents such as JP-A-2003-334046 and JP-A-2003-79339. If necessary, the dietary fiber-containing food material may be subjected to preliminary treatment such as cutting and blanching as described in JP-A-2002-218945. If the food-containing food material is not in powder form at the time of acquisition, it is preferable to use it as a powder of 75 zm or less.

Various manufacturing methods are known for the powder of ashitaba, for example, in JP-A-59-154935 and JP-A-2-231057. However, regardless of the production method, it is sufficient to use dried ashitapa powder. Ashitapa is a perennial plant of the Apiaceae family and is cultivated in Japan in central Honshu and in the Pacific Ocean side of the Kanto region. Ashitapa contains a lot of coumarins, chalcones and other antioxidant vitamins, and is effective for arteriosclerosis, constipation and anemia. The site to be used is not particularly limited, and all sites such as leaves, buds, stems, and fruits can be used.

Wheat young leaf powder, various manufacturing methods according to known literature (JP-A-7-241176, JP-A-2001-112435, JP-A-2002-58449, JP-A-2002-212, JP-A-2003-9812, JP-A-2003-178) Although it is known, regardless of the production method, it may be any dried wheat young leaf powder. Wheat young leaves refer to young leaves of barley, and specific examples thereof include young leaves of barley, wheat, rye, oat, barley and the like. Wheat young leaves are rich in vitamins, minerals, dietary fiber, etc., and absorb harmful substances, improve the intestinal environment, suppress cholesterol absorption, prevent postprandial blood glucose spikes, and activate superoxide dismutase (SOD). It is attracting attention as an effective health food ingredient.

[0010] Kale powders are known from the literature (JP 2002-186445, JP 2002-125612, JP

2002-119245, JP-A-2002-119239, JP-A-2002-112729, JP-A-2002-112701, and JP-A-2002-85010), various production methods are known, but regardless of the production method, dried kale powder is used. Should be fine. Kale is a perennial tree belonging to the Brassicaceae genus Brassica, and is originally an improved species of cabbage. The leaves are rich in vitamins and are effective in preventing gastritis and gastric ulcer, and improving liver function and constipation. Kale can be used without any particular limitation as long as it belongs to cruciferous kale. For example, various types of kale such as Siberian kale, Scotch kale, and Collard can be used.

[0011] Xylooligosaccharide refers to xylan (hemicellulose), a homopolysaccharide obtained from corn cob, cotton seed hull, or the like, to which several xyloses are bound. It is a white, slightly sweet, odorless, crystalline powder. For example, if the applicant has a trade name

It is convenient to use something commercially available as 95PJ. The effects of xylo-oligosaccharides are widely known as intestinal effects such as bifidobacterial growth activity, but also other effects include colorectal cancer prevention effects and mineral absorption promotion effects (Patent No. 3462535). ) Are known. The xylo-oligosaccharide content of the food should be monitored in each case by observing the state of granulation. The force may be determined as appropriate, but as a guide, it should be 3-20% by weight based on the total solid content. The xylo-oligosaccharide is added by mixing with the dietary fiber before the granulation step, or by adding, spraying, or pouring water in which the xylo-oligosaccharide is dissolved during the granulation step to the dietary fiber. Granulation can be performed by any method including a fluidized-bed granulation method and an extrusion-granulation method, and a fluidized-bed granulation method capable of obtaining a granulated material having good dispersibility can be suitably used. In that case, 1) xylo-oligosaccharide may be mixed with food material in advance and granulated by spraying with water, or 2) xylo-oligosaccharide dissolved in water may be added to food material during granulation. Spray and granulate. In the present invention, a desired granulated product can be obtained by any of the granulation methods. However, considering that the work is easy, the method 1) can be suitably used.

[0012] Whether the granules or fine granules produced by the method of the present invention are easily granulated as a product in the step of filling into sachets, which are less likely to be scattered as fine powder, and are granulated to some extent. preferable. Specifically, it is preferable that the granulation is performed so that the ratio of the fine powder of 75 / m or less becomes a certain value or less, for example, 50% by weight or less. Granulated granules or fine granules S Whether or not the granules have a particle size within this range can be confirmed by measuring the particle size distribution.

[0013] According to the method of the present invention, it is possible to use a binding agent other than xylo-oligosaccharides. Even without using such a binding agent, the dispersibility in water in the form of granules or fine particles can be improved. A good dietary fiber-containing food can be produced. The manufactured food can be easily packaged as a product with a low tendency to fly as fine powder.

[0014] The present invention also relates to a dietary fiber-containing food produced by the above method. Preferably, the dietary fiber-containing food of the present invention does not contain a binder other than xylo-oligosaccharide.On the other hand, as long as the image as a health food is not reduced, a general binder may be used. Can be used. When used as a normal solution such as carboxymethylcellulose / hydroxypropylcellulose, it is used in the form of a powder such as 3% or less, such as starch or corn starch. In this case, it can be added as long as it does not impair the fluidity when dissolved in water, for example, 10% or less.

[0015] Further, the dietary fiber-containing food of the present invention may contain additives or auxiliary components generally used in foods. For example, starch, lactose, crystalline cellulose, de- Kistrin, punorelane, guar gum, aspartame, xylitol, sucralose, mannitol, galactose as sweeteners, carotene, L-alcorbic acid, hy-tocopherol, rutin, lycopene, etc. as fortifiers. For example, by adding enzyme-treated rutin as an antioxidant component in an amount of about 0.1 to 10% by weight, the value as a health food can be increased.

[0016] The enzyme-treated rutin is obtained by converting a rutin and a rutin analog into a glycoside by enzymatic treatment, and examples of the rutin analog include quercetin, isoquercitrin, morin, myricitrin, and myricetin. Enzyme-treated rutin can be obtained, for example, by the methods described in JP-A-7-10898 and JP-A-2003-33164, and may contain not only enzyme-treated noretin but also a pharmaceutically acceptable additive. The amount of enzymatically treated rutin per composition may be determined based on an intake of enzymatically treated rutin of 5 mg 00 mg, preferably 1 mg (T300 mg) per adult per day.

[0017] The dietary fiber-containing food of the present invention may be provided with an indication regarding its function. Although there is no particular limitation on the method of displaying the function, examples of the method include a display on a food packaging, a container, a food description, a food advertisement, and the like. Examples of functions of the dietary fiber-containing food of the present invention include prevention or improvement of symptoms such as arteriosclerosis, anemia, gastritis, gastric ulcer, and constipation, improvement of liver function, suppression of harmful substance adsorption, improvement of intestinal environment, and diet effect. Inhibition of cholesterol absorption, prevention of a sharp rise in postprandial blood glucose, activation of superoxide dismutase, intestinal action including bifidobacteria growth activity, prevention of colorectal cancer, promotion of mineral absorption, or function based on antioxidant action It is.

The invention's effect

[0018] The method of the present invention can be easily granulated at the time of producing a dietary fiber-containing food, and generates less lump. Further, when granulating by the fluidized bed granulation method, water is used, so that scattering of powder can be suppressed. Furthermore, since a binding solution other than xylo-oligosaccharides can be used or can be reduced, the number of production steps can be reduced.

[0019] One of the effects expected from the consumption of a dietary fiber-containing food is a bowel-regulating effect. It is widely known that xylo-oligosaccharides have an intestinal action.The use of xylo-oligosaccharides in products using conventional binders is also important in terms of imparting intestinal action to foods containing dietary fiber. In comparison, it is preferable. In addition to intestinal action, xylo-oligosaccharides are known to have a colorectal cancer-preventing effect and a mineral absorption-promoting effect, and the dietary fiber-containing food of the present invention is extremely preferred in that these effects are expected. .

[0020] Since the dietary fiber-containing food of the present invention is in the form of granules or fine granules that are difficult to be scattered, it is easy to dissolve or disperse in water before ingestion. Since no binder other than xylo-oligosaccharide is used, the handleability when dissolved or dispersed in water is extremely good. Particularly when dissolved in a small amount of water, or when the granulated material is drunk directly in the oral cavity where only a small amount of water is present, there is an advantage in terms of good fluidity due to low viscosity. large.

[0021] The absence of a binder, which is a component other than dietary fiber, is also a health and taste advantage.

Example

Hereinafter, the present invention will be described with reference to examples, but these examples are not intended to limit the present invention.

Example 1

The effect of ashitapa powder as a dietary fiber material on the granulation properties of the amount of added syrup of xylo-oligosaccharide was evaluated. Approximately 200 g of the mixed powder shown in Table 1 was granulated by a fluidized bed granulator (FD-LAB- manufactured by Parek Co., Ltd.). After mixing and mixing for 2 minutes, water was sprayed at a rate of 1.0-1.5 gZmin and granulated for 30-50 minutes (product temperature: 24-30 ° C, intake air temperature: 30— 40 ° C). After drying for 5-10 minutes in the same apparatus, the granules were taken out and sieved with a No. 30 (500 zm) sieve to obtain granules.

[0023] The ratio of fine powder was evaluated as an index of granulation properties. That is, when the ratio of the fine powder passing through the No. 200 (75 μm) sieve was 50% by weight or less of the total amount, it was judged that the granulation property was good. This was set in consideration of the ease of handling when the obtained granules were packaged (bouch packaging).

Table 1 shows the results. The granulation properties of these compositions comprising ashitaba powder and xylo-oligosaccharide were evaluated. The case where the ratio of fine powder of 75 μπι or less was less than 50% was designated as Δ, and the case where it was 50% or more was designated as X. As a result, granulated products with a xylo-oligosaccharide ratio of 3% or more In the case, good granulation properties (evaluation result 〇) were shown (Table 1).

[0025] As described above, it has been shown that the production method of the present invention using xylo-oligosaccharide for granulation can provide a composition exhibiting good granulation properties without using a binder and an excipient.

Example 2

The effects of other dietary fiber materials and excipients were studied. The samples shown in Table 2 were used. The production method and the test method conformed to Example 1.

[0028] The results are shown in Table 2. The granulation properties were evaluated in the same manner as in Example 1. The case where the proportion of the fine powder having a particle size of 75 μm or less was less than 50% was defined as Δ, and the case where the proportion was 50% or more was defined as X. As a result, even in the case where barley young leaf powder, or both barley young leaf powder and acitapa powder were contained as a dietary fiber material, good granulation properties were exhibited by including xylo-oligosaccharide.

Good granulation properties were also observed when other excipients (crystalline cellulose, lactose) and a binder (carboxymethylcellulose) were used in combination.

[0029] As described above, it was shown that the technology of the present invention can be widely applied to dietary fiber materials. It was also found that it is possible to add excipients and binders within a range that would reduce the image as a health food.

With the compositions shown in Table 3, the effect of the manufacturing method was examined.

That is, granules were prepared by fluidized bed granulation or extrusion granulation. The production method in the case of fluidized bed granulation was in accordance with Example 1. However, in Sample 14, an aqueous solution in which xylo-oligosaccharide was dissolved in water was sprayed. On the other hand, in the case of extrusion granulation, the preparation amount was 200 mg, the mixture kneaded with an appropriate amount of water using a pestle and a mortar was extruded using a screen with a pore diameter of 0.8 mm, and dried on a shelf. (500 μm) to obtain a granulated product.

Table 3 shows the results. The granulation properties were evaluated in the same manner as in Examples 1 and 2. The case where the proportion of the fine powder having a particle size of 75 μm or less was less than 50% was indicated by Δ, and the case where it was 50% or more was indicated by X. As a result, all the samples showed good granulation properties.

These samples were evaluated for redispersibility. In the evaluation, 5 g of each sample was suspended in 150 ml of water, and after it was confirmed that the sample had become uniform, the sample was allowed to stand until solid and liquid separated. After the solid-liquid separation, shake the solution to make it uniform, and the time until the solid-liquid separation again is 20 seconds or more, <20 seconds if it is 10 seconds or more, and <10 seconds. Is defined as X.

[0034] Among these, the sample prepared by fluidized bed granulation had particularly good redispersibility in water having a large bulk density compared to the sample obtained by extrusion granulation.

[0035] Among the samples prepared by fluidized bed granulation, the ratio of the differential of 75 μm or less was below the target in both cases where the xylo-oligosaccharide was added as a powder and when sprayed as an aqueous solution. The granulation method has been found to be a suitable manufacturing method.
